So I have a Alpine SWR-1242D Subwoofer, also known as a Alpine Type-R 12" Subwoofer with Dual 4-Ohm Voice Coils. I know that since the subwoofer is a DVC 4-Ohm, I can run it in 2-Ohm or 8-Ohm configurations. I was intending to run it at 2-Ohms. Here is my issue, I cannot find a amp which is rated for around 500 Watts RMS. I was wondering if anyone had any recommendations. I was trying to get one as cheap as possible. I had looked at the Planet Audio AC1500.1M Anarchy 1500 Watt, but then I was not sure if there was a way to lower the watt output of that. Also, this is for a hobby project, so I'm trying to keep it as cheap as realistically possible.

Thanks for your suggestions!

  • As a note, I've just found a Boss Amp which also looks like a decent options, but is still a high wattage for this sub. But as long as I don't push max volume I might be fine? BOSS Audio R1100M – Matthew H. Sep 7 at 3:50

I do not believe that this is the correct site for asking consumer audio questions.

But the answer is simple.

You have 2 Voice Coils, each 4 Ohm. You should connect them in series, to make 8 Ohm.

The manual of the AC1500.M1 is detailing a 750 Watts output at a 4 Ohm load. With a 8 Ohm load this will be more in line with your 500 Watts rated speaker.
